A mysterious, imperious know-it-all promises to track down the world’s most sinister bad guys -- only he knows their identities -- in return for doing it all his way.

He’ll work only with a new agent who just happens to be beautiful and has a tormented past in addition to some possibly deep-held secrets of her own.

The FBI’s “Most Wanted” list? Pish-posh, small fish. “I’m Ahab,” declares Raymond “Red” Reddington (James Spader), who used to be an agent himself. “And if you want the whales on my list, you have to play by my rules.”

So here we go again, via NBC’s The Blacklist. Monday’s opening hour has one crackerjack action scene amid all the lack of cohesion and wildly quick deductions as to what a seething terrorist of the week named Ranko Zumani plans to blow up.

Spader also is afforded ample time to laugh haughtily or smile smugly. Meanwhile, rookie FBI agent Elizabeth “Liz” Keen (Megan Boone) wonders why her seemingly happy marriage and adoption plans have been all shook up. But Liz also has a tendency to display “narcissistic behavior,” as she explains to bossman Harold Cooper (Harry Joseph Lennix channeling the cadence of Barack Obama). Therefore “my colleagues call me ‘sir.’ They think I’m a bitch.”

The Blacklist seems to think a lot of itself, too. It’s a preening Peacock that looks expensive while calling further attention to itself with a big incessant drumbeat of a soundtrack. And NBC has positioned it right behind Monday’s two-hour editions of The Voice, likely ensuring ample sampling on opening night.

There’s also the kidnapping of a military general’s little daughter and a grisly torture scene that commences just after Red gets put up in a luxury hotel suite to the tune of Dean Martin’s now over-used “Ain’t That a Kick in the Head?” A couple of stabs to the thigh and side likely hurt even worse. After witnessing her loved one on the receiving end, an avenging Liz gets right up in Red’s grill. And around and around we go.

The Blacklist is watchable but patently unbelievable and increasingly unpalatable. Spader’s hoping to do tour de force here, but I’m already pretty weary of a character whose control freak partnership with an FBI ingenue is considerably less fun than Sleepy Hollow’s mismatched duo of a back-from-the-dead, time-traveling Ichabod Crane and a young female deputy with her own troubled past.

Those two are pursuing a headless horseman who’s learned how to fire automatic weapons in addition to swinging a lethal silver ax. On The Blacklist, the despot of the week will be of Red Reddington’s choosing. Because as he says, “Well, that was fun. Let’s do it again.”
